Title: Spectrophotometric system
IPC: G01J3/12
Filed: 1958-10-03
Abstract: 864,981. Photo-electric spectrometers. BECKMAN INSTRUMENTS Inc. Oct. 3, 1958 [Feb. 24, 1958], No. 31616/58. Class 40(3) [Also in Group XX] In a spectrometer of the type comprising both a refracting prism and a diffraction grating, a multi-lobe cam is provided to give the diffraction grating a series of forward and reverse angular excursions while the prism (or a mirror associated with it) makes a series of forward angular excursions. Thus a range of wavelengths is scanned but overlapping of grating images of different orders is avoided. As shown radiation enters the spectrometer through slit 10, is reflected from collimating mirror 10 passes through a dispersing prism 12 is reflected back by Littrow mirror 13 and again falls on the collimating mirror 12 and is brought to a focus in an intermediate slit 15 which is appreciably wider than the entrance slit. The radiation is then directed by flat mirror 16 to a second collimating mirror 17 which focuses on the grating 18, back to the collimating mirror and on to the exit slit 19. The emergent radiation falls on a radiation detector 20 the electrical output of which is connected to servo amplifier 22 to drive the pen 23 of a recorder 24. The diffraction grating is oscillated by cam 28 driven by motor 30 through a follower 31 mounted on the linkage shown which is pivoted at 34 and 35. The length of arms 33, 35 is adjustable so as to vary the excursion of the grating. Surfaces 54, 56, 57 produce the forward or working excursion of the grating during which the spectrum is recorded. While the grating is producing four excursions represented by the cam 28 a further cam 47 on the same shaft drives Littrow mirror 13 through a single excursion. This cam is so profiled that the mirror falls back a little between each grating excursion so that the recorded wave-lengths overlap. An alternative grating linkage is described (Fig. 2, not shown). Additional features. Potentiometer slider 74 coupled to motor 30 feeds an input to servo amplifier 75 which receives a position feedback voltage from a slider 77 driven by motor 76 which also adjusts the width of the input, output and intermediate slits. A cam 81 operates contacts 82, 86 to block recording of the signal during reverse portions of the grating movement, increase the speed of motor 30 during the movement and stop the instrument following a complete spectral run.

Title: Dc keyed high low select preference system for polyphonic electrical musical instruments
IPC: G10H1/22
Filed: 1973-07-05
Abstract: 1404909 Electrophonic musical instrument HAMMOND CORP 5 July 1973 [17 July 1972] 32035/73 Heading G5J To provide means of selecting the highest and/or lowest notes being played simultaneously on a group of keys, with the facilities for envelope shaping and economical key switching that DC keying allows, a key switch 14 for each note applies on closure line voltage 16 to its associated transistor A, B, C ... N, switching it into a conductive state and thus allowing the appropriate AC tone signal 20 to be fed to the output line 24-38. The transistors A-N for successive notes are connected to the output line at points separated by equal resistors 28-34; at each end of the line high input-impedance preamplifiers 26, 40 fed via similar resistors 22, 36 pass the signals to the instrument curcuits. The input impedance of each preamplifier is ten or more times the sum of all the output line resistances 22-36; each of these resistors being much higher than the resistance 18 to ground across its signal source 20. Any source keyed then has a very low impedance to ground as seen by a signal entering the output line from any other source; the only signals not short circuited to ground by other sources and able to reach the respective pre-amplifiers are the highest and lowest sources keyed at any one time. To sustain notes after their keys are released, capacitors may be connected between the lever sides 15 of the keyswitch contacts and ground, so holding the transistors conducting for a period after key release, during which external envelope shaping circuits may be active. Conventional circuits may be added to suppress a note being sustained as soon as further keys are pressed. The circuit may be used with only one preamplifier, connected to the appropiate end of the output line to identify either the highest or the lowest key pressed. Lines 15 allow other circuits in the instrument to be operated by the key switches 14, unaffected by the circuits of the invention.
